Despite reports that cast doubt on its provenance, a "Captain America" chopper purported to be the last remaining motorcycle used in the filming of the 1969 movie "Easy Rider" sold at auction Saturday night for $1.35 million -- or just more than $1.6 million after auction fees are included. The chrome-heavy, star-spangled Harley-Davidson panhead, ridden by actor Peter Fonda in the ground-breaking movie directed by his co-star Dennis Hopper, was owned by Los Angeles real-estate agent and movie memorabilia collector Michael Eisenberg.
